Andreas Lehmkühler updated PDFBOX-1013:
---------------------------------------
Description:
The problem is that the toString method is called on objects which may have
been returned as null
The suggested fix to this, in the attached patch is to check if null, then
write an empty string
String s = "Shading " + shadingname + "\n"
+ "\tShadingType: " + getShadingType() + "\n"
+ "\tColorSpace: " + sColorSpace + "\n"
+ "\tAntiAlias: " + getAntiAlias() + "\n"
+ "\tCoords: " + (getCoords() != null ? getCoords().toString() :
"") + "\n"
+ "\tDomain: " + (getDomain() != null ? getDomain().toString() :
"") + "\n"
+ "\tFunction: " + sFunction + "\n"
+ "\tExtend: " + (getExtend() != null ? getExtend().toString() :
"") + "\n"
+ "\tRaw Value:\n" +
